DROP DATABASE [IF EXISTS] When restoring Databases

We encounter a very strange MariaDB innodb failure and almost all databases where empty.

Jetbackup couldn't restore only Databases and queue was "partially completed" because of this.

Databased exists but only their names. With zero data. Just DB names.

A trigger to "DROP if DB exists" should be nice.

We had to select DBs and check which were empty, like that:

SELECT S.SCHEMA_NAME FROM INFORMATION_SCHEMA.SCHEMATA S
LEFT OUTER JOIN INFORMATION_SCHEMA.TABLES T ON S.SCHEMA_NAME = T.TABLE_SCHEMA
WHERE T.TABLE_SCHEMA IS NULL;

and then DROP them. And after dropping them only then jetbackup could restore it.

There are already triggers like:

"terminate account before restore"

"merge backup data"

"suspend account after restore"

But nothing for Databases.

A "Drop if exists" should do the trick.
